Embodiment 1

[0022] A method for hydroponic cutting propagation of rose apples. Select the semi-lignified new shoots of rose apples that grow vigorously, have good buds, and are disease-free, and trim them into 8-10 cm double-leaf and double-bud branches as cuttings, and cut the lower part of the cuttings into an inclined plane. Submerge the base 2cm of the cuttings into 60mg / kg ABT2 rooting powder solution and soak for 60min, then take it out and dry it for later use.

[0023] The preparation of the nutrient solution: the raw material content of the nutrient solution is: 1 / 2WPM+IBA0.4mg / L+GGR1.0mg / L+sucrose 10g / L+agar 2.0g / L+activated carbon 1.0g / L, add citric acid solution to dissolve the nutrient solution The pH was adjusted to 5.8.

[0024] Before cutting, choose a box made of glass as the cutting container in the cutting room. The cutting box is 20cm wide, 50cm long, 20cm deep, and the glass is 0.5cm thick; pour nutrient solution into the cutting container, and the depth of the nutrie...

Embodiment 2

[0026] A method for the hydroponic cutting propagation of rose apples. Select the semi-lignified shoots of rose apples that grow vigorously, have good buds, and are disease-free, and trim them into 8-10 cm double-leaf and double-bud branches as cuttings, and cut the lower part of the cuttings into an inclined plane. Submerge the base 3cm of the cuttings into 60mg / kg ABT2 rooting powder solution and soak for 80min, then take it out and dry it for later use.

[0027] The preparation of the nutrient solution: the raw material content of the nutrient solution is: 1 / 2WPM+IBA0.8mg / L+GGR1.5mg / L+sucrose 10g / L+agar 3.0g / L+activated carbon 2.0g / L, add citric acid solution to dissolve the nutrient solution The pH was adjusted to 6.0.

[0028] Before cutting, choose a box made of glass as the cutting container in the cutting room. The cutting box is 25cm wide, 55cm long, 20cm deep, and the glass is 0.5cm thick; pour the nutrient solution into the cutting container, and the depth of the nu...

Embodiment 3

[0030] A method for the hydroponic cutting propagation of rose apples, which selects vigorously growing, good-bud, and disease-free young shoots of rose apples that are lignified in the same year, and prunes branches with double leaves and double buds of 8-10 cm as cuttings, cuts the lower part of the cuttings into an inclined plane, and Submerge the base 4cm of the cuttings in 60mg / kg ABT2 rooting powder solution and soak for 80min, then take it out and dry it for later use.

[0031] The preparation of the nutrient solution: the raw material content of the nutrient solution is: 1 / 2WPM+IBA1.2mg / L+GGR2.0mg / L+sucrose 10g / L+agar 4.0g / L+activated carbon 1.5g / L, add citric acid solution to dissolve the nutrient solution The pH was adjusted to 5.9.

[0032] Before cutting, choose a box made of glass as the cutting container in the cutting room. The cutting box is 30cm wide, 60cm long, 25cm deep, and the glass is 0.5cm thick; pour the nutrient solution into the cutting container, and...

Abstract

The invention discloses a water culture cutting propagation method of syzygium jambos. The method is characterized by including the procedures of collection and treatment of a shoot for cutting, preparation of a nutrient solution, preparation of a cutting container, water culture, cutting after-treatment, and acclimatization and transplanting. A one-year-old semi-lignified or lignified syzygium jambos shoot which grows robustly, is provided with a good bud and is free of diseases is selected, pruned, and inserted into the cutting container filled with the nutrient solution for water culture, the culture conditions are controlled, acclimatization and transplanting are conducted after the shoot for cutting which grows into a young root is obtained, and a syzygium jambos seedling is obtained. The problem that cutting seasons are limited by time is solved, cutting propagation can be conducted all the year round, the culture period is short, root taking is quick, environment controllability is good, the culture conditions are stable, and the survival rate of the shoot for cutting is more than 93%; the method is suitable for large-scale production and can be widely popularized, and good economic benefits, social benefits and ecological benefits are achieved.

Description

technical field [0001] The invention belongs to the field of plant cutting propagation, and relates to the cutting propagation of rose apples, in particular to a hydroponic cutting propagation method of rose apples. Background technique [0002] Rose apple, (Syzygium jambos (L.) Alston), is an evergreen tree of Myrtaceae, also known as water apple, fragrant fruit, ring drum, wind drum, bell fruit. Rose apple has a good ornamental effect and is a traditional and commonly used material for making bonsai. Rose apples have few pests and diseases and strong adaptability. They are naturally distributed in the dry and barren mountainous lands of Hubei, Hunan, Jiangxi, Zhejiang, Anhui, Fujian, Guangdong, Guangxi, Guizhou and other places south of the middle and lower reaches of the Yangtze River. Drought-resistant and barren, it is a rare excellent woody ornamental plant resource integrating excellent ornamental and environmental adaptability. Because rose apple has obvious charac...
